Computer Simulation of Creation and Motion of Edge Dislocations in Face Centered Crystals

Complete and dissociated edge dislocations were created near the center of the surface (101) of aluminum small crystals whose surfaces are (111), ( 111 ), ( 1 01), (10 1 ). ( 1 2 1 ) and (1 2 1). Molecular dynamics with N-body embedded atom potentials were used. Higher stress is needed to create a complete edge dislocation than to create a dissociated dislocation.
